Embodiment
With reference now to accompanying drawing, Fig. 1 shows the cloud meter for the virtualization that the embodiments of the present invention are operated wherein
Calculate the schematic diagram of environment 100.Although being not specifically illustrated in Fig. 1, the cloud computing environment 100 of virtualization can be included largely
Server computer, the data and application that these server computer trustships are connected by Real Time Communication Network.The cloud of virtualization
The virtual version of equipment or resource in computing environment 100 is divided into the one or more for supporting to calculate and storage resource is shared
Performing environment.In this manner, physical resource (such as processor, memory, network bandwidth and storage device) is conceptualized as using
The virtual tool with improved ease of manageability is utilized in efficient resource.
Monitoring and abnormality detecting program 105 are virtual for operating characteristics (such as network congestion and resource excessive use) monitoring
The cloud computing environment 100 of change.This can include the cloud computing environment 100 of the excessive use monitoring virtualization for resource and inspection
Survey the congestion for accessing resource.In operation, monitoring and abnormality detecting program 105 can detect when using/cloud user along its input/
When exporting (I/O) path experience excessive deferral, which is in acceptable level in advance.In one embodiment, it is if super
Go out scheduled visit delay threshold value, then monitoring and abnormality detecting program 105 can detect excessive deferral.Monitoring and abnormality detecting program
105 can be any commercially available program, and such as IBM TIVOLI storage productivity center, TIVOLI monitor work
Tool or VMWARE monitoring instruments.
The cloud computing environment management assembly 110 of virtualization communicates virtual to reduce with monitoring and abnormality detecting program 105
Network congestion and/or resource excessive use in the cloud computing environment 100 of change.The cloud computing environment management assembly 110 of virtualization
Other can be performed and safeguard and monitor operation to preserve the operation of the cloud computing environment 100 of virtualization.Although monitoring and exception
Detect program 105 and be illustrated as different computing systems in Fig. 1 with the cloud computing environment management assembly 110 virtualized, but this
A little components may reside within identical systems.
In the various embodiments of the present invention, monitoring and abnormality detecting program 105 and the cloud computing environment pipe of virtualization
Reason component 110 can be used for the cloud computing environment 100 of monitoring virtualization, detection when cloud management person runs isomery migration session and exist
Perform the network congestion occurred during migration session and resource excessive use and according to migration session to network congestion or resource mistake
Spend the contribution utilized and throttle those migration sessions to alleviate I/O delays.As used herein, the migration session that throttles is typically to move
Move the reduction of the migration transmission rate of object, data or structure that session embodies.
Fig. 2 shows cloud meter of the cloud computing environment management assembly 110 via virtualization by virtualization shown in Fig. 1
Calculate the schematic diagram that the cloud management person in environment initiates isomery migration session.As used herein, migration session includes being related to number
Any management role according to transmitting and using cloud resource.Isomery migration session is migration different types of object, data or knot
The migration session of structure.For example, Fig. 2 is illustrated in virtual machine (VM) 200, file 205, volume 210, moving of performing on resource N 220
Move session.In the example present, the migration session of these multiple types coexists in cloud, and can share common resource
(for example, the network switch or shared storage rear end).In fig. 2, VM 200, file 205 and volume 210 are in the example present
The entity being migrated.For example, by VM 200 from machine A migrate to machine B can correspond to by X data volumes from machine A transmit to
Machine B.Migrated file 205 can correspond to from machine C transmit Y data amount to machine D.The migration of volume 210 can pass through phase
Characterized like mode.Under any circumstance, all migration sessions are true " data transfers " occurred in cloud (or data center), and
And each data transfer will utilize cloud resource (for example, storage device needs to distribute CPU to carry out incoming I/O operation).Therefore,
For management purposes, not being can be with the workload of cloud user generation by cloud Client-initiated these " data transfers " set
Shared resource and its performance can be influenceed.Because final goal is preferably service cloud user, so if these management numbers
Negative effect is played according to application of the utilization of resources of transmission to cloud user, then should be throttled.High-ranking military officer those skilled in the art
It can arrive, these shown isomery migration sessions are that can be performed in the cloud computing environment 100 (Fig. 1) of virtualization in fig. 2
The example of some type of migration session limited without being intended to.
Isomery migration session can be by some attribute characterizations.One attribute be by migration perform function type (for example,
Volume, file, VM), it represents the target obtained by performing migration.For example, cause one that a VM is moved to another VM
Migration session, which can have, to be used to reduce focus or reduces the function of congestion in cloud.Cause and move storage box (for example, virtual disk)
Another migration for moving to another storage box can have the function of being used for cached data.
Another attribute is the value of the session after completion migration session.Substantially, each function of being performed by the session exists
The backward cloud computing environment of its completion provides certain benefit or value.Therefore, the value of migration session depends on the function or mesh of migration
's.For example, if migration type is that wherein target is that the volume that will be seldom looked at reassigns to more cheap storage device
Storage volume migrates, then a kind of method of calculated value can be determined that：siBe worth=| target I/O density-I/O density | * sizes.
If migration type is that wherein target is to reduce the file migration from hard disk to cache of file access delay, this is moved
Moving the value of session can be calculated as：siValue=cache hit probability.Pay attention to, cache hit probability is used by oneself
The new request at family will require the probability of this specific file.For example, if file is a large number of users by the popular movies of request,
This file may be considered that with big " hit probability ".Therefore, in the example present, this popular file can be placed in height
In speed caching rather than slower hard disk, to help quickly to access.On the other hand, if another file has low prevalence
Degree, and therefore there is small hit probability, then it can be placed in slow hard disk, so as to (have higher life for those prevalences
Middle probability) file save cache (there is limited size) space.Generally, the function of migration session determine its value to
The mode for being calculated and being assessed.In one embodiment, the high level for the migration session with similar purpose can imply that
Less throttling.
Other attributes that can be used for characterizing migration session from other isomery migration sessions are the residues of the migration session
Size and migration rate.As used herein, remaining size is typically that the remainder for migration is left when identifying bottleneck
According to amount.Migration rate is to perform the speed of migration.
Migration type, value, remaining size and the migration rate of function only can be used for migration session from other isomeries
The example for some attributes that migration session is characterized and distinguished, and it is not intended to limit the embodiments of the present invention.This area skill
Art personnel will be appreciated that (such as the ownership of service impact, delay tolerance, migration session is (for example, who initiates this to other attributes
One migration session) etc.) it can be used for each side sign isomery migration session and throttling migration session described herein.
Fig. 3 shows that what can be used in the cloud computing environment management assembly 110 (Fig. 1) of virtualization is used to throttle in void
The isomery for being run simultaneously in the cloud computing environment 100 (Fig. 1) of planization and sharing the isomery migration session of same asset set moves
Move the schematic diagram of session throttling instrument 300.As shown in FIG. 3, isomery migration session throttling instrument 300 includes monitoring assembly
305, it is supervised when isomery migrates operation exception (because I/O caused by the excessive use of resource, resource congestion etc. postpones)
Survey the cloud computing environment 100 of virtualization.Monitoring assembly 305 can with monitoring and abnormality detecting program 105 (Fig. 1) with reference to work with
It is determined that whether any I/O paths in the cloud computing environment 100 of virtualization after migration session is initiated undergo excessive deferral.Prison
Survey the cloud computing environment that component 305 can receive monitoring and abnormality detecting program 105 virtualizes via known push/pull technology for detection
The instruction of excessive deferral in 100.Once monitoring assembly 305 receives operates normal I/ before isomery migration session is initiated
Initiated beyond the instruction of scheduled visit delay, isomery migration session throttling instrument 300 can to troublesome migration in O paths
The throttling of session.
Throttling to troublesome migration session identifies the cloud computing environment 100 for going to virtualization from mark component 310 first
In the I/O paths of the resource for being experienced by excessive I/O delay start.Mark component 310 can then identify to be had along I/O paths
The bottleneck of excessive deferral.As used herein, along I/O paths there is the bottleneck of excessive deferral to refer on the I/O paths most
Serious excessive use and it should be considered first to alleviate the shared resource of delay.In one embodiment, it is bottom-up
Mode can be by since storage volume and working until main frame, and will have excessive deferral (that is, beyond predetermined threshold)
The first shared resource (for example, storage pool, storage disc subsystem, network equipment) carried out labeled as bottleneck.In another implementation
In mode, bottleneck can deviate its average response by identifying compared with other resources on the I/O paths on congestion I/O paths
Time maximum equipment is pointed out.Once bottleneck is identified, it is possible to identifies all contributive migrations through this bottleneck
Session.
Virtual virtually being provided to physics to physical resource map information of resource in cloud computing environment 100 comprising virtualization
Source map information component 315 can be used for mark through this bottleneck and to its contributive all migration session.In a reality
Apply in mode, this information can be obtained by inquiring about virtualization layer.For example, in terms of Storage Virtualization, equipment will pass through by
Virtual disk is mapped to physical disks to perform Storage Virtualization, and this mapping relation information is stored in the table that can be queried
In.As described below, it is virtual to be used to pass through to physical resource map information using virtual to physical resource map information component 315
Each migration session is calculated to " the contribution part " of bottleneck to distinguish moving for the shared identical equipment or resource for being identified as bottleneck
Move session.
Virtually to physical resource map information component 315 by using virtually being obtained first to physical resource map information
List through this bottleneck and to the contributive isomery migration session of congestion determines each migration session to the bottleneck
Contribute part.In one embodiment, the list through the bottleneck and to the contributive migration session of congestion or set can
To be represented by S.In one embodiment, for each contributive migration session s in set Si, the attribute quilt of the session
For determining the priority of each migration session in terms of to bottleneck contribution, it transfers to determine to gather around the amount being throttled to alleviate edge
The delay in the I/O paths of plug.Attribute can include the migration type for the function or purpose for representing migration session (for example, volume, text
Part, VM), the value (purpose for depending on migration) of the benefit of migration session is captured after completion, leaves migration meeting to be done
The contribution part of the remaining sizes of words and instruction session to the contributive amount of bottleneck.
In one embodiment, it can be numerical value to contribute part cp, and the numerical value can be calculated as：si.cp=it is current
Migration rate × fraction (e.g., 1,1/2,1/4 ...).Because isomery virtually arrives physical resource mapping, the migration session in S can be with
Different loading sections is contributed bottleneck.As an example, consider that migration A and B contributes to the storage subsystem of congestion.
Migration session A can contribute bottleneck all loads, and migration session B due to it is different it is virtual be rolled onto physical disks mapping and can be with
The 2/3 of its total load (60MB/s) is only contributed bottleneck.According to embodiment described here, the solution that effectively throttles can be with
Throttling migration session A is more than migration session B, and this is due to A bigger contribution part.Migration with less contribution partial value
Can be by less throttling, this is due to that this can unnecessarily delay its deadline and have subtle effects to alleviating bottleneck.
Orifice union 320 can be used from the isomery migration session virtually generated to physical resource map information component 315
List and each session contribution part come the isomery session that throttles.Generally, orifice union 320 is by isomery migration session list
In each migration session migration rate throttling corresponding to the following amount：Migration session perform function type, with
The associated value of migration session and the contribution part to congestion at the I/O paths of mark.Other attributes used in throttling can
To include the remaining size and migration rate of each migration session in list.
Orifice union 320 can throttle migration session to obtain predetermined initial general objective stream using the attribute being indicated above
Amount is reduced.In one embodiment, predetermined value can be configured to (for example, 400MB/ by making a reservation for initial general objective speed reduction
s).In other words, after congestion or excessive use is detected, cloud management person can be first attempted to polymerization migration rate or speed
Reduce scheduled volume (for example, 400MB/s).This total speed is reduced then can be by the contributive list of bottleneck or set S
All sessions share.
Orifice union 320 can be assigned it to first by the function according to each migration session or purpose sorted group come
Predetermined initial general objective flow is reduced to each session in the session being assigned in isomery migration session list.Pass through this side
Formula, the migration session with common function is assigned to similar sorted group, and the isomery with different purpose functions migrates meeting
Words are assigned to different sorted groups.In one embodiment, the migration session in each sorted group can be according to its function
And its contribution part is prioritized.
Orifice union 320 can determine that the polymerization migration rate of migration session in each sorted group is each to determine now
Group contribute to how many to bottleneck.In one embodiment, polymerizeing migration rate includes each isomery migration in each sorted group
The summation of the transmission rate of session.For example, if group 1 has two sessions that transmission rate is 60MB/s and 40MB/s, use
In the rate of polymerization of the group be 100MB/s.
Next, orifice union 320 predetermined initial general objective flow minimizing speed can be assigned to it is every in sorted group
Individual sorted group is directed to the group stage speed each organized reduction target (that is, the amount that each session should be reduced in group) to obtain.
In one embodiment, it is proportional to the polymerization migration rate determined for the group that each group stage speed reduces target.For example, such as
Fruit is present with three groups (group 1, group 2, group 3) that rate of polymerization is 500MB/s, 250MB/s and 250MB/s, then 400MB/s
Total speed reduction can be allocated as follows：The rate of polymerization of group 1 is reduced to 200MB/s；The rate of polymerization of group 2 is reduced to
100MB/s；And the rate of polymerization of group 3 is reduced to 100MB/s.
It is if desired, skilled artisans will appreciate that logical to being easy to expand to proportional distribution mechanism mentioned above
With weight assignment solution, wherein there is each group weight to capture other commercial interest points, such as business of this migration group
Industry value, the risk/punishment/critical condition for postponing this business group etc..By this mode, total speed is reduced can be according to its power
Weight is shared by all groups.
Once it is determined that group speed reduces target, this group of speed is reduced Target Assignment and arrived by orifice union 320 can
Each migration session in this group.In one embodiment, the interior distribution of this group can be implemented as follows.At each group
Interior, all sessions are according to following measurement descending ranking：Wherein si.rs it is current residual size；si.cp it is tribute
Offer part；And siIt is worth (si.value) it is regarded as the value of the calculating for migration.All sessions in group are sorted it
Afterwards, the ranking in the list that orifice union 320 can sort according to it determines that the speed of each session is reduced.In an embodiment party
In formula, the session that a kind of simple greedy mode can be used in the list by sequence suspends until reaching a group speed reduction one by one
Target.
The each group of stage speed that orifice union 320 can then be reduced in target according to group stage speed reduces target and initiated newly
Migration session.Pay attention to, when new migration session is initiated during throttling, the new migration session can be from reservation default rate
(for example, 60MB/s) starts.When migration session is completed during throttling, it is every into sorted group target can be reduced with repeating groups speed
The distribution of individual migration session.
After the migration session that throttles, if the congestion of bottleneck still has, possible orifice union 320 must be by always
Target flow minimizing speed increases scheduled volume.Generally, after reaching initial target speed and reducing, the cloud computing environment of virtualization
Management assembly 110 will inquire about monitoring and abnormality detecting program 105 to check whether throttling eliminates the response of congestion and bottleneck
Whether the time is fallen on below predetermined threshold.In another embodiment, predetermined stop criterion is being reached (for example, for migration meeting
The minimum-rate requirement of words) after, monitoring and abnormality detecting program 105 can be checked.If it is determined that bottleneck still has,
Then total speed further can be reduced target by migration manager increases predetermined increment, for example, further reduce 50MB/s and
Be applied to isomery migration session throttling instrument 300 for throttle again with the increased general objective flow minimizing speed of institute into
The migration session of ratio.Pay attention to, by the minimum-rate of migration session be arranged to zero simply imply if must if all migrations
Session should be suspended.
Throttling and again throttling, which can be continued until, to be solved congestion/excessive use or meets predetermined stop criterion,
For example, the minimum-rate requirement of migration session is reached and has not allowed further to throttle.The work even if isomery migration session throttles
Tool 300 can exclude a bottleneck, and this iteration may also must handle the application for still exceeding predetermined threshold along I/O paths
Access delay.If the access delay that throttling scheme excludes a bottleneck and the application along I/O paths still exceeds predetermined threshold
Value, then this additional step is by iteration above-mentioned steps.In other words, although throttling through the above way can be solved along I/O roads
The excessive use of one equipment in footpath, but another equipment is likely to become new bottleneck and by penalty on the I/O paths
To unacceptable level.Therefore, additional iteration will identify new bottleneck and continue throttling process until the problem is solved,
Or predetermined stop criterion is satisfied, and do not allow further to throttle.
Fig. 4 shows the flow for the operation for illustrating the throttling isomery migration session according to an embodiment of the invention
Figure 40 0.First, 405, multiple isomery migration sessions are initiated in the cloud computing environment of virtualization.It is every in migration session
Individual migration session runs in the cloud computing environment of virtualization and shares same asset set simultaneously.Isomery migration session by with
Properties sign, these attributes can include perform migration session function or type, by perform migration session obtain

It is any in cloud computing of the cloud computing environment of monitoring virtualization in virtualization when performing migration session 410
The delay of Energy Resources Service.415, any resource for the excessive I/O delays of experience that mark is gone in the cloud computing environment of virtualization
I/O paths.Next, 420, carry out on be along which resource of I/O paths or equipment the bottleneck of excessive I/O delays really
It is fixed.Fig. 5 is shown in which that resource is identified as the example of the bottleneck in specific I/O paths.In the example present, volume controller is stored
It is identified as the bottleneck with exclamation icon.In the example present, gross migration speed is reduced to 600MB/s from 1000MB/s,
And the migration session through this bottleneck is assigned to, to alleviate excessive I/O delays.
Referring back to Fig. 4, the virtual of resource arrives physical resource map information quilt in 425, the cloud computing environment of virtualization
For obtaining the list to the contributive isomery migration session of bottleneck at the I/O paths of mark.Referring again to Fig. 5, virtually arrive
Physical resource map information can be used for obtaining the migration session set to storage volume controller contribution load.There is tribute for each
The migration session offered, its attribute are recorded to determine the priority each migrated, and it transfers to determine the amount that will be throttled.
Referring back to Fig. 4, after isomery migration session list is obtained, the migration rate of each session in 430, list
It is throttled the amount corresponding to the following：Function type that migration session performs, the value associated with migration session and indicate
The contribution part for the quantity that migration session is contributed bottleneck at the I/O paths of mark.Virtual due to isomery is reflected to physical resource
Penetrate, the migration session in isomery migration session list can contribute different loading sections to bottleneck.For example, such as institute in figure 6
Show, volume migration A and B contributes to the storage volume control device subsystem of congestion.Own however, migration session A contributes to bottleneck
Load (being in this example 60MB/s), and because the different virtual physical disks that are rolled onto map migration session B only by its total load
2/3 (40MB/s) of (60MB/s) contributes to bottleneck.Therefore, because A more shared greatly part, effective throttling solution described here
Certainly the scheme migration session A that can throttle is more than migration session B.By less throttling, this is for migration with smaller contribution partial value
There are subtle effects to alleviating bottleneck because this can unnecessarily delay its deadline.
Fig. 7 illustrates another example of the throttling isomery migration session according to the embodiments of the present invention.In the figure 7,
The storage volume controller for being marked with exclamation icon is identified as bottleneck.In order to alleviate this bottleneck, gross migration speed is from 1000MB/
S is reduced to 600MB/s.The 1000MB/s can be assigned to some classification of the classification of type of the function according to its execution
Group.Especially, the 1000MB/s can be allocated according to the contribution part to bottleneck.In the example present, group 1 in session from
500MB/s, which changes, arrive 300MB/s, and the session in group 2 changes to 150MB/s from 250MB/s, and organize session in 3 from
250MB/s, which changes, arrives 150MB/s.That is, the migration rate in group 1 is reduced 200MB/s, and the migration rate organized in 2 is reduced
Migration rate in 100MB/s, and group 3 is reduced 100MB/s, contributes to 400MB/s total flow to reduce.
Total flow reduces each migration session that can be then assigned in the migration session in group.Because group 1 is subtracted
Few 200MB/s, this needs to be assigned to all sessions in this group.Similarly, 100MB/s needs to be assigned in these groups
Each group in all sessions.Using manner as described above, 400MB/s needs are proportionally assigned to it and contributed
Part.Because group 1 has twice of 2 and Fig. 3 of group speed, therefore it is to organize 1 and need twice of 2 and Fig. 3 of group.Such as institute in this example
Show, group 1, volume 1,3 and 5 seems more important than volume 2 and 4 for bottleneck, and is therefore allocated 100MB/s, and rolls up 2 and 4 and divided
With 0MB/s.VM distribution can be led to using each migration session according to the ranking of shown equation in file set and group 3 in group 2
Similar manner is crossed to be allocated.
Referring back to Fig. 4, after throttling, 435, if bottleneck still has, migration session may need to be weighed
New throttling.Especially, the amount of targeted rate reduction may need to be increased is less than threshold value, Huo Zheru until the response time of bottleneck
Fruit not yet meet minimum-rate requirement then targeted rate reduction amount may needs be increased.Fig. 8, which is illustrated, wherein will always move
Move speed from 1000MB/s be reduced to 600MB/s after the example that still has of bottleneck.In this case, tasting for bottleneck is alleviated
Examination can be by being reduced to 400MB/s to attempt by gross migration speed from 600MB/s.Can be with for these steps described in Fig. 4
The problem of being repeated until is solved, or can be stopped when reaching predetermined stop criterion (for example, minimum-rate requirement).
Above flow illustrate with being throttled using the reactivity of the contribution part of virtualization information and session to bottleneck
